OpenZeppelin Relay

OpenZeppelin Relay

Defender Relay sends transactions via HTTP API, automating smart contract operations securely.

What is OpenZeppelin Relay?

OpenZeppelin created its Defender Relay service to allow users to send transactions via a regular HTTP API. Defender Relay provides a gasless meta-transaction relay that ensures a seamless and cost-efficient experience. For developers, there is no need to monitor transactions or use a backend script to secure private keys because the protocol takes care of everything from resubmissions to private key secure storage to the signing of transactions.
